BIO 151 FINAL PAPER TESTED QUESTIONS
WITH DETAILED SOLUTIONS STUDY
MATERIAL
●● What are the characteristics of life?
Answer: The characteristics include organization, metabolism,
homeostasis, growth, reproduction, response to stimuli, and adaptation
through evolution.
●● What are viruses?
Answer: Viruses are microscopic infectious agents that can only
replicate inside the living cells of an organism.
●● What is the scientific method?
Answer: A systematic approach to research that involves formulating
hypotheses, conducting controlled experiments, and analyzing results.
●● What is a scientific theory?
Answer: A well-substantiated explanation of an aspect of the natural
world that is based on a body of evidence and has stood up to repeated
testing.
●● What are the units of the metric system for volume?
,Answer: The metric units for volume include liters (L) and milliliters
(mL).
●● What are the units of the metric system for length?
Answer: The metric units for length include meters (m), centimeters
(cm), and millimeters (mm).
●● What are the units of the metric system for mass?
Answer: The metric units for mass include grams (g) and kilograms
(kg).
●● What are the units of the metric system for temperature?
Answer: The metric unit for temperature is degrees Celsius (°C).
●● What is the structure of an atom?
Answer: An atom consists of a nucleus containing protons and neutrons,
surrounded by electrons in orbitals.
●● What are radioisotopes?
Answer: Radioisotopes are isotopes of elements that are unstable and
emit radiation as they decay.
●● What are energy levels and electron distribution?
, Answer: Energy levels are regions around the nucleus of an atom where
electrons are likely to be found, and electron distribution refers to how
electrons are arranged in these levels.
●● What are chemical bonds?
Answer: Chemical bonds are the forces that hold atoms together in
compounds, primarily ionic and covalent bonds.
●● What is the difference between hydrophilic and hydrophobic?
Answer: Hydrophilic substances are attracted to water, while
hydrophobic substances repel water.
●● What are the properties of water?
Answer: Water has unique properties including cohesion, adhesion, high
specific heat, and being a universal solvent.
●● What is pH?
Answer: pH is a measure of the acidity or basicity of a solution, with
lower values indicating acidity and higher values indicating alkalinity.
●● What are the four major classes of organic molecules?
Answer: The four major classes are carbohydrates, lipids, proteins, and
nucleic acids.
